-Referring to the drawings in detail, .particularly Figures 1 to 15,inclusive, the tractor or machine comprises a main frame A having spacedparallel side sills Ill, being longitudinally of the tractor or Amachineat the vunder sides of these sills are the bearings, one being indicatedat II for the housing I2 of a wheel axle unit I3 'involving adifferential I4. The axle unit I3 sup- The wheels I have associatedtherewith brake `drums I8 embraced by brake bands I1 of the expansibleand con-- mission shaft 25 involving transmission gearing (not shown)and confined within a transmission housing 28. The transmission shiftlever is indicated at 21 for regulating thevspeed of driving operationand reversal of the traveling direction of the tractor or machine. Thevtransmission mechanism has connection by ,a pinion 28 with a mastergear 29 of the differential I4 and in this manner the wheels I5 aredriven.

On each bearing II is built a pivotal sleeve 38 for the end 3| of acultivator.beam or bar 32.

seeds-i4 over are confined within a shield casing 3l suitably madesecure infplace, the inner wall 33 oi.

this casing being slotted at 43 to provide a clearance for the powershaft 2| of the motor 20 when the carrier I3 is shifted on the rodtracks I8 for a purpose presently described.

dling relation thereto are detachable yokes 41.

Each yoke 41 is pivoted to a pin 48 and is formed with a medial eye 48in which is loosely fitted a link 55.- These links 58 are looselyvconnected at 5I to the brackets 34 and on the rotating of the rods 45the cultivator beams or bars 32 'can be laterally adjusted' to vary therelationship of the ground working elements at opposite sides of thetractor with respect to each other.

the 4rotatable mounting thereof.

Pivotally supported at opposite sides of the frame A are swinging arms52 which loosely en- This sleeve has pivoted thereto a releasing latch33 engageable with the pivot end 3| for the detachable fitting of thebar or beam 32 to said bearing I I. Each cultivator beam or bar 32cargage the lower .ends'of the rods 45, each being tted with an abutment53 for action upon the arms 52 next thereto. The arms 52 have connectedtherewith links 54 engaged with brake band operating levers 55. Thus onthe shifting of one ofthe rods 55 one brake band I1 will be operated'andsimultaneously on the shifting of the otherrod the other brake band I1will be operated. By shifting both rods 45 the two brake bands I1 willbe operated simultaneously. In this manner by operating one of the brakebands I1 the tractor will be caused to pivot under its own'power forturning movement then by operating both brake bands simultaneously thespeed of forward travel through braking action may be had of thetractor.

Connected with the frame 4I is a support 55 'having a guide eye-likekeeper 51 through which works a shift lever 58 having connection with arocking arm 59 swingingly pivoted at 80 to the frame A and to which isconnected a throw link 6I, the same being also connected at 62 to thecarrier I9. This lever 58 when shifted moves the carrier I9. On movementof the carrier in one direction the belt 23 will be slackened about thepulleys 22 and 24 to shut o ff power from the motor 20 to the wheels I5.To eliminate the sticking of the belt 23 to the pulley 22, there isprovided in the shield casing 38 adjustable guides $3r these beingadapted to act upon the belt on the slackening thereof to raise thelatter out of the belt grooves in the pulleys 22 and 24 and thuseliminating the sticking of the belt therein.

The lever 58 is formed with a toothed lrack 84 to enable adjustable,latching vof this lever by the keeperl 51, the lever being acted uponby a. leaf spring urging the toothed rack into latching engagement withthe said vkeeper 51. Connected with the arm 53 is a coiled retractllespring 88, being also connected with the frame A. The purpose of thisspring is to have the carrier I3 shift when the lever 58 is releasedfrom the keeper 51 for the slackening of the belt 23 and thus cuttingoff drive from the motor 20 to the wheels I5 of the tractor.

The rods 45 are -slidable in angle irons 43 in addition to ateos- 8lalso has fixed thereto a crank 'III in which is swiveled an eye 1Ithrough which plays a coupling rod 12. 'I'he rod is engagedin the ear'I3 formed on la cross .connecting bar 'I4 loosely engaged at 'Il withthe said rods 4l and resting against abutments I8 upon these rods. Thuswhen one rod 4l is longitudinally shifted with respect to the angle iron43 the bar 'I4 will be rocked. This rocking action will be ineffectiveon the pin 09 for depressing the spring 8l. However, when both slidablerods 48 are longitudinally shifted in the angle irons 43 together thebar 'I4 will recede or move therewith, actuv ating .the pin 60 fordepressing the spring 88 and thus the lever I8 will become unlatched atthe rack 34 from the keeper 81. concurrently the spring 88 becomesactive for the shifting of the carrier I3 with the motor 20 thereon andin this way slackening the belt 23. Should it become necessary, thelever 88 can be manually pulled when it is released from the keeper I'Ifor the shifting of the carrier I8 and thereby power will be shut offfrom. the wheels Il of the tractor.

` Each rod 48 is turned by the handle 48 andalso longitudinally shiftedin the angle bar 43 m'anually as common thereto. Thus each brake band Ilcan be applied separately or together and also when both brake bands areapplied for braking action through lthe shifting of the rods 4l thepower from the motor 20 will be cut olf from the wheels I5.

'I'he coupling rod I2 carries the .adjustable nuts 'I'I and 13,respectively, thel nut .'I8 being next to the ear 13 while the nut 11 isnext to theeye 1I. I 2.

The pulley 24 at its outer side carries a belt pulley 'I8 so that powercan be taken off to out-A side machinery from this driven pulley 24.

In Figure 15 of the drawings. there is shown a slight modificationwherein the driven pulley 80 is formed with a female clutch part 8|coactingl with a. male cone clutch part 82 splined or keyed on thetransmission shaft 33, the male clutch part 82 being shifted by a throwyoke 84 operated from the link 88 in substitute for the link 84. Theclutch parts 8| and 82 coacting'with each other enable the clutching andunclutching operations between the power connections of' the motor 20and the wheels I8 of the tractor.

-At the longitudinal center ofthe tractor main frame A between the sidesills Il'is detachably and flexibly mounted the forward end of the draftpole |88 of a riding attachment or sulky including Aground wheels I 0|Journaled upon turnable axles '|32 and |03, respectively. Their turningstems are of different lengths and the shorter of these is rotatablysupported in a vertical bearing |34 while thelonger of the stems isjournaled in the vertical bearing |08, there being a cross sill |88between these bearings, which are a part thereof. The shorter stem ofthe axle I 02 is fitted with la bell crank lever |01,

one of its` arms having pivotally connected" turned for the steering ofthe riding sulky in its association with the tractor. This crank arm IIIis connected with the stem of the axle |03 so that. the said stem can bevertically shifted in the bearing |38 therefor without simultaneousmovement of the said arm yet the arm turns the said axle. The arm II Icarries a set screw |I2 for the adjustable fastening thereof to the stemof the axle |03., The stem of the axle |03 is susceptible of verticaladJustment in its bearing |06 so as to raise or lower the wheel IOIcarried by said axle |83 relative to the wheel I0| carried by the axleI02-to avoid lateral tilting wheelgll on the axle |03 travels in afurrow on the working I of the tractor.

I8 has its hub 86 flxed to a sleeve 81 splinedfv to one section of theaxle while the other wheely is fixed to a sleeve 88 loose on the othersection of the said axle. The brake drum. I8 is fixed to the sleeve 8lof one wheel while the other brake drum is onthe sleeve 88, thus itbeing seen from this figure of the drawings that either wheel may beindependently braked. The brake Mounted at/the longitudinal center ofthe trac-L i y tor on the hanger having the-bars95 'and 86 -is a clevisI|3 with which isassociated a universal coupling Joint |I4 for araisingan'd id wering rod I I8 which is adjustably pivoted at II8 to anextension I| 'I of a throw lever I I8 equipped witha e hand release;spring thrown, latching evice IIS bands I'I on the drums I8 arecontrolled indiengageable with a rack keeper segmenv |20 fixed to anattaching pin |2I.

The lever I I8 is for the purpose of impartingtilting the riding sulky for. bringing the 'ground -working tools 8| and88 into engagement with the ground or clear of the same. the clearedposition thereof being shown in Figure 22 of the drawings. This leverII8 is manually operatedby the rider of the sulky or an operator of themachine.

In Figures 29 and 30 and 3l of the drawings there is shown a furthermodication wherein a hanger |36 is substituted for the hanger involvingthe bars 95^and 96 and this hanger |36 is fastened to the sills |0 ofthe tractor by `brackets |31. The hanger |36 has coupling at |38 withthe pole |00 and also coupling |39 with beam or bar for the groundworking tools. This l pivot end is detachably pivotally fastened at |42in its pivotal fitting in the sill I0, being a subfstitute structure forthat shownin Figures 9 and 10 of the drawings and involving the parts30, 3|, 32 and 33, respectively.

It should be apparent in the association of the riding sulky withthe'tractor that the said sulky is automatically guided or turnedconcurrently with the turning of the tractor. Further, one wheel of thesulky can travel in the open furrow and side tilting of the said sulkyavoided.

Additionally, the tractor as well as the riding sulky, can be verticallyraised andlowered together for clearing of the ground working tools fromthe ground or the bringing of the sameinto working position. 4

'I'he wheels of the tractor in the modified form thereof are rubbertired at |43 and similarly the sulky Wheels |0| are rubber tired at |44.

As heretofore indicated, each cultivator beam o'r bar 90 in the modifiedform of construction illustratedv in Figures 16, 26 and 27 of thedrawings carriesa single tool 9| so that there will be only one tool oneach side of the tractor which makes it much easier to handle than ifall the ground digging tools were carried by these beams 90 vand thelatter operated from the rods |34, it being apparent from Figures' 1 and3 of the drawings that the beams or bars 32 support gangsv of tools orclusters thereof and these bars are laterally adjusted through the rods4 5 from the hand grips 4 6.
